The Food and Drug Administration last week sent a warning letter to Todd Whidden and his company, Flu and Cold Defense LLC, about the marketing of its product, GermBullet.

According to the GermBullet website, the product is intended to "reduce illness-causing bacteria, cold and flu viruses and fungi."

However, the FDA claims the company is misleading its customers and the product hasn't been vetted by professional research.

The FDA said in its letter, in part, that the company makes "false and misleading promotional statements on your website regarding the product." The letter goes on to say that it's illegal "to advertise that a product can prevent, treat or cure human disease unless you possess competent and reliable scientific evidence."

WPBF 25 News tried to contact Whidden and the company for a comment, but so far there has been no response.
